Product Details

Apply to soaking wet hair. This will evenly distribute the product.

Flip your head upside down. Take the Merwave Cast Foam and rake it through gently. Then take small sections of your hair and scrunch them up towards your scalp. Squeeze slightly to get rid of excess moisture to help the drying process.

You then scrunch in a small quantity of Protect Gel to hold that definition in place. This lightweight gel won’t weigh your waves down unlike heavier gels. Simply diffuse or air dry as normal.
